Rei-Ki – consists of two syllables in the Japanese language.  ‘Rei’ can be used to describe the ‘universal energy’ or ‘the cosmic energy’.  ‘Ki’ can be translated to describe the life force flowing through all living things.

‘Reiki is an ancient and profoundly simple system of ‘laying on of hands’ healing derived from Tibetan Buddhism’1

Just for today I will give thanks for my many blessings.
Just for today I will not worry.
Just for today I will not be angry
Just for today I will do my work honestly
Just for today I will be kind to my neighbour and every living thing 2
